As I wrote above, I rather see it differently. The original intent of Enums
was to have string representation in most cases. So this should be the
default, since most of the time this is what the user wants. No one really
passes explicit s/r codes. In the minority, specialized cases, where the
user wants to force int-like formatting, then the number should be given
and not the member name. This would also be consistent with non-decimal
formatting options like %x and the .format equivalent.
